My invention relates to new and useful improvements 1n an electric ironofthe type .in which a removable, interchangeable heating element isused so that when one is burned out.,darnaged or otherwise impaired. itmay be removed' and replaced by a new one.

The principal object of the invention lis to provide this characterwhich Vmay be readily and quickly taken apart by afperson unskilled.

in mechanical structures, such as a housewife for instance, the heatingelement changed and the parts reassembled and fastened together. 1 f 4 lAnother object of the invention is to provide a. separable ironor aniron having separable units detacl'iably fastened together.

A further object of my invention is to provide an exceedingly simple andeffective arv rangement for fastening the parts together which willsimultaneously force one element, unit or part forwardly of andr towardthe other element insuring a tight joint.

A still further object of this invention is to utilize parts of theironv as a support or. stand when the iron is temporarily set asideduring the time articles, which are being pressed, are rearranged orchanged.

Yet another object of the invention is to produce an electric ironcomprising a base having a recess to receive and hold removable heatingelement, .said base having an undercut hole at one end and screwarranged at an angle at the other end, a top provided with lugor tonguearranged at an angle for registration with thefundercut hole and havinga beveled surf-ace' in which is a slot to register with the screw. ahandle carried by the top and a wing nut for mounting upon the screw toengage the bevel surface whereby the top may be tightly but removablysecured to the base7 said wing nut in conjunction with the handle actingas a stand or support when the iron is tilted.

"With these ends in view, this invention consists in the details ofconstruction and combination of elements Yiereinait'ter set forth andthen specifically desie'nated by the claims.

In order that those skilled in the art to which this inventionappertains, may understand how to malte and use the same7 1 willdescribe its construction in detail, referring by numerals to theaccompanying drawing simple andcoi'npact device of Aforming a. part .ofthis application, in which y .Fig'. l isa/sectional side elevation of anelectric iron embodying my invention.

Fig. 2 is a side elevation thereof in a tilted position..

Fig. 3 is a plan view of the base with the top removed.

Fig. fl is an end viewrof thetop.

Fig. 5 is an enlarged side elevation of the wing nut.

In carrying out my invention as here embodied, 2 represents the base ofan iron having smoothing surface 3 and provided with a. recess 4 toreceive and hold aremovable interchangeable heating elemento of anysuitable well known construction. At one end of the base, preferably theforward end, is formed an undercut hole 6 or in other words the hole isformed at an angle to the smoothing surfaceof the base the sameprojecting downwardly and forwardly. At the other or rear end of thebase is located a screw or bolt 7 it being mounted in the base in anysuitable manner preferably by casting the base about it and this screwbolt is arranged in an upwardly and outwardly projecting positionsubstantially at the same angle as the undercut hole 6. This bolt`receives the butterfly or wing nut 8 the eX- tremities of the wings 9in a certain case acting as feet asV will be later described.

The top 10 to which is attached the handle l1 carries the electricalconductors including contact posts l2 and this top is adapted to setupon the upper edge of thebase preferably with a sheet of asbestos 13interposed between them, said asbestos sheet being secured to the innersurface of the top. Projecting from the bottom of this top elementadjacent one or its forward end is an angular lug or tongue 14.projecting downwardly and outwardly for registration with the undercuthole 6 while at the other or rear end of said top is formed a bevelsurface 15 Vljnfng at an acute angle to the bottoni ory inner face ofthe vtop and the smoothing sur.- face of the base and in this surface orsaid other end is formed an opening i6 preferably in the form of a slot,as plainly shown in Fig. li, so as to readily register with the screw orbolt 7 and when the top is in place upon the base, as shown in Fig. l,the butteriiy or wing nut 8 will engage the bevel surface 15 to securelydraw the parts toing as a temporary stand or support for the' ironduring the time the worlr is being changed or rearranged therebypreventing the iron from scorching' the object on which it is set andeliminating the necessity of using a eepf 'ate or independent Standwhich being` of metal ofttimes has a tendency to mar or otherwise damagethe Smoothing Surface of the iron. 'Y

From the foregoing description it will be noted that when it'beconleanecessary to remove or change the heating` element the butterfly or wingnut is backed ott' of the Screw iern'iitting the rear or that end of thetop engaged by Said nut to be lifted' and the tongue 14 withdrawn fromthe iunlercutfhole 6 so that said top may be Separated and entirelyremoved from the base giving ac.- cess to the heating' element so thatit may be removed and reduced or another substituted therefor.

After thc necessary change has been made the tongue la is insert-ed inthe ruuilercut hole 6 and the opening;` 16 caused to register with theScrew or bolt 7 then by drawing up on the butterfly or wing nut 8 itwill be moved into engagement with the bevel end or surface l5 of thetop and because of said bevel end and the annular portion of the screwor bolt 7 Said top will be forced end wise or forwardly of the' base andin conjunction with the tongue latv will cause the top to be forceddownwardly or toward the baee thereby forming; a tight joint between thetwo members.

Of course l do not wish to be limited to the exact vdetalle ofconstruction as herein shown as these may be varied within the limits ofthe appended claims'without departing from the Spirit of my invention.

Having thus fully described my invention, what I claim as new and usefulis l. An iron comprising a base, a top coacting therewith, means fordetachably connecting the top to the base, `said means including abutterfly or wing nut7 said nut when in place having its wingsprojecting transversely of the iron and a handle fixed the forward endof the top for regietration" with the undercut hole. Said tongue pro'(itl jecting downwardly and lforwardly at an` angle to the inner face ofsaid top, a wingl f nut having' threaded connection with the bolt andadapted to engage the bevelV eurface of the top for forcing` the vlatterforwardly and in conjunction with the tongue coacting with the undercuthole forcingA the top toward the base to produce a tight joint.V

.Said wing nut when flight/cned lying trane versely of the iron and ahandle "aarried by the top for operating the iron and coop `eratinf:with the wing' nut when the' iron is tilted to act as a stand or`Support.

3. An iron comprising a base having an undercut hole at its forward end,a coacting top member having' an opening at its rear end and providedwith a bevel Surface in the region of said opening, a tongue on theforward end of the top member tor ineen tion in the-undercut hole, aninclined bolt at the rear of the bottom for registration with theopeningin the top member. and means having tl'ire-aded engagement withthe bolt and bearing` on thelfnev'eled eurface of `'said top to forcethe latter .into close contact with the bottom.

ln testimony whereof, I have hereunto aixed my signature.
